Nearly all sponges are sea animals, but one family, the Spongillidae, live in fresh water. There are five British species, two common ones being the River Sponge (Ephydatia [or Spongilla] fluviatilis) and the Pond Sponge (Euspongilla [or Spongilla] lacustris).Both these species form greenish or yellowish encrusting growths over the surfaces of stones and by: 3.

EDITOR'S PREFACE. Annandale's volume on the Freshwater Sponges, Polyzoa, and Hydrida contains an account of three of the chief groups of freshwater organisms.

Although he deals mainly with Indian forms the book contains an unusually full account of the life-history and bionomics of freshwater Sponges, Polyzoa, and Hydrozoa.

The majority are marine, but there are about species of freshwater sponges, including twenty-seven to thirty species found in North America north of Mexico. Although the majority of sponges live in marine habitats, one family, the Spongillidae, is found in fresh water.

However, in most water bodies populations of freshwater sponges are sufficiently sparse that they are unlikely to play a major role in ecosystem functions (Reiswig et al., ). Yet.

First, then, all fresh-water sponges which have been described at the present date are of a silicious character; that is, their skeleton structure or frame-work does not consist, as in the familiar marine sponges of commerce, of an elastic network of tough fibres - but of lines of fasciculated flint-needles, about one one-hundreth of an inch in.

Phylum Porifera ("pori" = pores, "fera" = bearers) popularly known as sponges, a group simple organisms. Sponges are sessile organisms found attached to a substratum. The majority of sponges are marine, living in seas and oceans. There is one family of fresh water sponges (Family Spongillidae).

Unlike Protozoans, the Poriferans are multicellular. As mentioned they need phyto/bacterio plankton and micro-organic particles in the water to feed on. They also need mature tank water and low nutrients to thrive as they are quite sensitive organisms.

Air bubbles can get trapped in their pores which can kill them so you have to be extra careful not to expose them to the air. Full text of "Fresh water sponges; a monograph" See other formats.
